Another Access Control What we Missed: Review Exploit Defense From AC view

Presented at ToorCon San Diego 16 (2014), Oct. 26, 2014, 3:30 p.m. (20 minutes)

Today, many different approaches are used by Industry to stop 0-day, but attack techniques are rapidly improved. From Ret2Libc to ROP, existing defense solutions have many challenges to stop novel exploit techniques before it’s published. In this talk, we will review the new techniques published by hackers in past 2 years to create powerful exploit even without ROP and rethink the new defense approaches from access control view.
